Remarks
 Only the current family type is editable using the methods in  FamilyManager  . If you want to modify the properties of any family type, it must be set to be the current type first. This value will be    a null reference (  Nothing  in Visual Basic)  if there is no type in the family. In order to modify parameter values, you will need to create one using  NewType(String)  .
